Photosynthesis EoTT revision powerpoint

Chloroplasts

Organelles found in plant cells that perform photosynthesis and contain chlorophyll.

Photosynthesis

The process by which green plants and algae make their own food using sunlight, carbon dioxide, and water.

Carbon Dioxide

A gas taken in by plants during photosynthesis, combined with water to produce glucose and oxygen.

Glucose

A simple sugar produced by photosynthesis, used by plants for energy and can be stored as starch.

Aerobic Respiration

A chemical reaction that transfers energy to cells using glucose and oxygen, producing carbon dioxide and water.

Anaerobic Respiration

A form of respiration that occurs in the absence of oxygen, producing lactic acid and less energy than aerobic respiration.

Root Hair Cell

Specialized cells in plant roots that absorb water and minerals from the soil, with a large surface area for efficient uptake.

Circulatory System

The system responsible for pumping blood throughout the body, consisting of the heart, blood vessels, and blood.

Plasma

The straw-colored liquid component of blood that transports nutrients, waste products, hormones, and helps distribute heat.

Red Blood Cells

Cells that transport oxygen from the lungs to body tissues and contain hemoglobin to facilitate oxygen transport.

Veins

Blood vessels that carry deoxygenated blood back to the heart, have thinner walls than arteries, and contain valves.

Arteries

Blood vessels that carry oxygenated blood away from the heart, have thick muscular walls, and transport blood under high pressure.

Lactic Acid

A byproduct of anaerobic respiration that can build up in muscles during intense exercise, causing pain and fatigue.

Photosynthesis Word Equation

carbon dioxide + water → glucose + oxygen.

Nutrients in Plants

Minerals from the soil that plants use to build complex molecules needed for survival and growth.

Respiration

A chemical process that releases energy from glucose in all living cells, vital for growth, repair, movement, and maintaining temperature.
